About Mazda Service at Riley Auto Care

Mazda occupies a unique position in the automotive world — producing vehicles that are genuinely fun to drive while delivering outstanding fuel efficiency and long-term reliability. The Mazda3, CX-5, and MX-5 Miata consistently earn top marks from automotive critics and owners alike, and the SKYACTIV technology platform that underpins the modern lineup is a genuine engineering achievement. At Riley Auto Care & Transmissions, we service the complete Mazda lineup with the care and precision these vehicles deserve.

Mazda's SKYACTIV-G gasoline engines achieve near-diesel compression ratios for improved efficiency without sacrificing performance. These engines require clean, high-quality oil and precise maintenance intervals to perform at their best. We use the correct 0W-20 specification oil and follow Mazda's maintenance schedule to keep SKYACTIV engines running efficiently. For CX-9 and CX-5 owners with the turbocharged 2.5T engine, we pay particular attention to turbocharger oil supply and intercooler condition.

Mazda's i-ACTIV AWD system — found in the CX-5, CX-9, CX-30, and CX-50 — uses predictive algorithms to distribute torque before wheel slip occurs. Regular transfer case and rear differential fluid service keeps this system operating as designed. For MX-5 Miata enthusiasts, we provide the performance-oriented maintenance that keeps this iconic roadster sharp and responsive. Serving Mazda drivers throughout the area, we deliver the quality service your vehicle was engineered to receive.
